Quartigod (¼ divine, via Aeacus son of Zeus). Aeacid king of the Myrmidons at Phthia; Argonaut and Calydonian hunter; won the sea-goddess Thetis by holding her through her shape-shifting. Their divine-attended wedding on Mount Pelion — and the golden apple cast there by Eris — began the chain that led to the Trojan War. Father of Achilles by Thetis; the mortal-tier father whose Nereid wife makes his son half-divine.
